DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to
Measure the amount and specific gravity of urine collected individually for each subject,
The present invention relates to a urine test apparatus that stores at least a part of urine collection for each subject, and particularly to a urine cassette that dispenses urine and a urine test apparatus that is characterized by a urine cassette rack that accommodates a plurality of urine cassettes.

[0002]

2. Description of the Related Art This type of urine testing apparatus includes a urine collection container, a nozzle for sucking urine in the urine collection container, a plurality of urine cassettes for dispensing and storing urine in the urine collection container, and moving the nozzle. Some include nozzle moving means. The urine cassette usually has an opening whose upper part is largely opened, through which a nozzle is inserted and urine is injected from the nozzle. Usually, a plurality of urine cassettes are collectively accommodated in a urine cassette rack, and a cleaning liquid is put into the urine cassette from an opening when the urine cassette is washed.

[0003]

However, since the ordinary urine cassette has a structure in which the upper part is largely open, the urine in the urine easily jumps out of the opening or spills when carrying. , Very hard to hold,
This makes carrying more cumbersome. Further, since the urine cassette has no accommodation direction with respect to the urine cassette rack, when the urine cassette is accommodated in the urine cassette rack, the accommodating direction is likely to be wrong.

[0004] Accordingly, the present invention has been made in view of such conventional problems, and there is provided a urine testing apparatus provided with a urine cassette and a urine cassette rack in which a liquid is hardly spilled, easily carried, and a storage direction is hard to be mistaken. The purpose is to provide.

[0005]

According to one aspect of the present invention, there is provided a urine testing apparatus, comprising: a urine collecting container; a nozzle for sucking urine in the urine collecting container; A plurality of urine cassettes for dispensing and storing urine, and a nozzle moving means for moving a nozzle, wherein the urine cassette has a liquid inlet and outlet partially open at the top,
It has a handle portion protruding upward from the upper portion, an inclined surface descending from the entrance to the lower portion inside the upper portion, and a chamfered portion at the lower portion.

In this urine test apparatus, the urine cassette has a liquid inlet / outlet which is partially open unlike the conventional urine cassette, so that the urine in the urine cassette hardly spills out or spills when it is carried. In addition, since it is sufficient to hold the handle when carrying, it is easy to carry, and the urine adhering near the entrance is hardly attached to the hand, so that it is also clean. When urine is flushed out of the urine cassette or when the urine is washed with a washing liquid, the urine or the washing liquid runs out better, and the liquid does not flow along the outer wall of the urine cassette.

According to a second aspect of the present invention, there is provided a urine analyzer, comprising: a urine collection container, a nozzle for sucking urine in the urine collection container, a plurality of urine cassettes for dispensing and storing urine in the urine collection container, and a plurality of urine cassettes. A urine cassette rack that accommodates side-by-side containers, and a nozzle moving unit that moves a nozzle, wherein the urine cassette has a liquid inlet / outlet partially opened at an upper part, a handle part protruding upward from an upper part, and an upper part inside. The urine cassette rack has an inclined surface descending from an entrance to a lower part, a chamfered part at a lower part, and the urine cassette rack has a cassette accommodating part for accommodating each urine cassette, and a lower part having a chamfered lower part of the urine cassette. And a pair of slit holes at the front and rear portions of each cassette accommodating portion, and both ends are removably fitted to the pair of slit holes, respectively, and installed in each cassette accommodating portion. Be done And having a stopper member and a projecting portion having a rear portion through hole.

In this urine testing apparatus, in addition to the configuration of the urine cassette, the urine cassette is accommodated in the urine cassette rack so that both chamfered portions of the urine cassette and the urine cassette rack correspond to each other. If the two chamfers do not correspond, that is, if the urine cassette is stored in the opposite direction, the urine cassette cannot be stored in the urine cassette rack, so that the urine cassette can be stored in the correct direction. Further, by attaching a stopper member to the pair of slit holes of the cassette accommodating portion of the urine cassette rack, the urine cassette cannot be accommodated in the cassette accommodating portion provided with the stopper member, and the urine cassette cannot be accommodated in the urine cassette rack. There is no mistake in the storage position.

By making the entire shape of the urine cassette flat (claim 3), the urine cassette rack accommodating a plurality of urine cassettes side by side can be downsized, especially when a larger number of urine cassettes are accommodated. However, it is possible to reduce the size of the urine test apparatus. When the entire shape of the urine cassette is flat, by connecting the substantially central portions of both sides of the urine cassette integrally (claim 4), the side portion expands when urine is put into the urine cassette. In addition to preventing urine cassettes, the urine cassette can be reinforced.

When the urine cassette rack is set in the apparatus, the stopper on the apparatus side is inserted and engaged with the through hole of the projecting portion, and the urine cassette rack is fixed to the apparatus. Thus, the urine cassette rack cannot be taken out of the apparatus carelessly, and mischief can be prevented.
